Most microphone covers and windscreens are made from foam (often described as dense or high‑density foam). Outdoor 'furry' wind muffs use high‑density artificial fur over foam. Larger isolation shields typically combine sound‑absorbing EVA foam with a perforated metal backing for structural support and improved acoustic performance.
Many isolation shields are collapsible or foldable for easier breakdown and transport. Individual foam windscreens and furry muffs are very lightweight and compact—examples in listings show small covers weighing roughly 0.02 to 0.05 pounds—making them easy to pack or store.
Isolation shields are designed to fit most standard mic stands and commonly use the universal 5/8" microphone threading. Many shields also include mounting hardware or adjustable support bars to attach securely to a stand.
Fit depends on the product and microphone type: some covers are made for lavalier mics, others fit small compact mics (examples up to about 2.5 × 40 mm L×D), some are sized for shotgun microphones (up to roughly 8 cm long), and others fit portable recorders (examples around 3 × 1.5 inches). Check the product dimensions against your microphone for a proper fit.
